摘要
In even code division multiple access method (CDMA) considered to be suitable for radio transmission using mobile stations such as a cellular phone or the like, at present it is difficult to secure a strict orthogonal relationship, so that received signals cannot be separated from each other completely, thereby other mobile stations being an interfering source. Further, if an application band width for use is defined, the other band widths cannot be applied. The multi-carrier modulation section places a plurality of carriers continuously within a preliminarily allocated band and modulates the individual carriers separately. An adder synthesizes a plurality of the carriers modulated by the multi-carrier modulation section. An antenna transmits a synthesized output from the adder. IMAGE
